Our algorithm uses gradients of an objective function as basis vectors for forming model updates. The extended set of basis vectors provides explicit de-mixing of gradient components corresponding to different medium parameters, for example P-wave velocity and anisotropy. Coefficients of the basis vector expansion are determined in a way that explicitly accounts for leakage (or crosstalk) between different physical parameters. Performance of the method is illustrated with a synthetic data example.
